I've won a lot of games that got drawn out/locked down to simple draw go's because I had fire bolts for 25+ direct damage. Bolt is more versatile than Rage Pot since it offers player damage and can destroy stronger creatures in stalled-out situations. Also, since all of your creatures are high cost (7 and 10), you'll be saving up quanta to the point where bolt will kill X/6 where as Pot can only kill X/5. Puts certain dragons and other nasties in your CC range when you need to race and makes a world of difference on occasion.
